Benefits of technology

Enables efficient and effective closure of arteriotomies without the need for prolonged bed rest or intense pressure, allowing for immediate mobilization and reducing tissue trauma by directly closing the puncture site using a stapler mechanism within the vessel lumen.

Problems solved by technology

When the staple is deployed, the staple perforates or fractures the frangible cap.

Embodiment Construction

[0055]Low Profile Guiding System

[0056]Specific embodiments of the present disclosure are now described with reference to the figures, where like reference numbers indicate identical or functionally similar elements. The present disclosure is directed to a device and method for closing an arteriotomy after a procedure in which a vessel was punctured to gain access to the vessel lumen. FIGS. 1-10 show cross-sectional views of body tissue 100 with a vessel 102 disposed therein. FIG. 1 shows a procedural device 108, such as a balloon catheter, disposed partially within a lumen 104 of vessel 102. The distal end of procedural device 108 is shown riding along a guidewire 110. Procedural device 108 passes through a procedural sheath 106, which maintains access to lumen 104 through a tissue track 101 in tissue 100 and arteriotomy 132 in the wall of vessel 102.

[0057]As the intra-luminal procedure, such as balloon angioplasty, is completed, procedural device 108 is removed from vessel 102 and ...

Abstract

A closure device for an arteriotomy includes an elongate tube having a distal opening. The elongate tube has least two opposing longitudinal slots and a pair of opposing corners defined where each slot meets the distal opening. A staple is disposed within the tube, the staple having at least two opposing legs aligned with the at least two slots. Each slot is pinched together adjacent the distal opening such that the opposing corners of each slot converge to cover the tip of the respective staple leg to guard the staple tips against contact with the tissue track. The corners of each slot are separable to permit the respective staple leg to pass there between.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to system and method for closing an opening in a vessel wall after a medical procedure, and in particular, to a system and method for closing a puncture arteriotomy after an intra-luminal procedure such as catheterization.BACKGROUND OF THE INVENTION[0002]Catheters / catheterization procedures for diagnosis or treatment of cardiovascular and / or peripheral vascular diseases are well known, and typically involve the Seldinger technique to make insertions through layers of tissue and through a wall of the femoral artery. After a diagnostic or interventional catheterization, the arteriotomy puncture formed by the catheter or introducer sheath must be closed. The puncture opening in the artery typically ranges from 5 French (0.0655 inch, 1.67 mm) such as for a diagnostic angiography procedure to as large as 30 French (0.393 inch, 10.00 mm) for an interventional procedure such as implanting an inferior vena cava (IVC) filter.
